Antivirus Interference

This error may occur due to virtualization being disabled or core isolation being enabled.

Antivirus software can block or interfere with drivers and loaders. This guide explains how to temporarily disable antivirus protection to ensure products load correctly.

Why This Is RequiredAntivirus software commonly blocks drivers, injectors, and loaders. This includes Windows Defender and third-party antivirus providers. Interference can cause products to fail to load, drivers to be deleted, or errors during execution.External antivirus providers such as Malwarebytes, Avast, Bitdefender, Kaspersky, etc. must also be fully disabled. Simply disabling Windows Defender is not sufficient if another provider is active.Disable Windows Defender (Temporarily)

1. Open Windows Search and search for Windows Security

2. Click Virus & threat protection

3. Click Manage settings

4. Disable the following:

   • Real-time protection

   • Cloud-delivered protection

   • Automatic sample submission

   • Tamper Protection

Disable Third-Party AntivirusIf you have an external antivirus installed:

• Open the antivirus control panel

• Fully disable protection and shields

• Ensure no background services remain running

Some antivirus software continues running services even when “disabled”. If issues persist, you may need to temporarily uninstall the antivirus.Re-enable AntivirusYou may re-enable all antivirus protections after the driver has successfully loaded and the product is fully running.Re-enabling antivirus before the driver is loaded may result in files being quarantined or the driver failing to load.
